Embodiment 1

[0063] In a low-temperature environment of -70°C, lay dry ice particles with an average particle size of 0.1mm on the display device, then apply sealant on the periphery of the dry ice particles, and stick the package cover on the display device.

[0064] Finally, the packaged display device can be placed at room temperature, and the dry ice can be sublimated into carbon dioxide gas, which can be used as a protective gas.

Embodiment 2

[0066] 20g of calcium carbonate particles were dispersed into 40g of water to form a slurry.

[0067] The slurry is coated on the periphery of the effective display area of ​​the display device. Then dry at 60°C for 10 min. Then, sealant is coated on the periphery of the dried gas degassing gas, and the packaging cover is pasted on the display device.

Abstract

The invention relates to a display device. The display device includes a display device and a packaging cover packaged outside the display device, a packaging cavity is formed between the display device and the packaging cover, and a protective gas is filled in the packaging cavity; the protective gas is selected from carbon dioxide or hydrogen. The display device can inhibit the damage of the water vapor and oxygen in the external air to the display device, thereby improving the service life of the display device. The invention also discloses a packaging method for a display device, which includes placing analyte gas around the effective display area of ​​the display device; vacuum packaging the display device with a packaging cover around the analyte gas; making the analyte gas release a protective gas, The protective gas is selected from carbon dioxide or hydrogen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a packaging method for the display device. Background technique [0002] AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode), as a new type of display device, has high chromaticity, high contrast, wide viewing angle, high brightness, self-illumination, fast response, and can realize Features such as flexible displays have been widely used in mobile phones and media players. AMOLED display devices have high requirements for water and oxygen barriers, so they usually need to be packaged before use. However, the packaging method of the traditional AMOLED display device is to use glass packaging or film packaging in a vacuum environment, so that the space between the AMOLED display device and the packaging cover on its surface is in a vacuum state. However, the packaging cover obtained by using the traditiona...
